SPRING Tooi Filed Dec. 12, 1935 IIIIIH! ma 3 A v ll/jg 6 a ATTORNE Patented May 26, 1936 UNITED STATES PATENT OFFICE SPRING TOOL Joseph Allievi, West New York, and Henry 1 Claim.

This invention relates to spring tools, and more specifically to a tool for applying and removing springs.

An object of the invention is to provide such a tool constructed at one end for the insertion or removal of the hooked end of a coiled spring into a hole or opening, and constructed at its opposite end for the positioning or removal of the hooked end of the spring over a pin or post.

A further object is to provide a tool of this character which will limit the movement of the hooked end of the spring on the tool, and which is so shaped as to form a claw to engage a pin or post and cause, when the tool is properly manipulated, the hooked end of the spring to ride easily off the claw on to the pin or post.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawing Figure 1 is a view somewhat diagrammatic and in elevation, illustrating the braking elements of a wheeled vehicle;

Fig. 2 is a view in elevation of my improved tool, the claw end of the tool being in longitudinal section;

Fig. 3 is a view in elevation similar to Fig. 2 and at right angles to Fig. 2;

Fig. 4 is an end view looking at the left-hand end of Fig. 3;

Fig. 5 is a fragmentary View in elevation, illustrating the position of the claw end of the tool in applying the hooked end of the spring to a pin or post;

Fig. 6 is a similar View showing the other end of the tool in position to move the hooked end of the spring into a hole or opening.

We illustrate in Fig. l of the drawing a brake assemblage, indicated generally by the reference character A, as it is one of the broad uses of our invention to employ a tool which is especially adapted for the assembling and coupling engagement of retractile springs in an assemblage of this kind.

The tool comprises a bar I, having any suitable handle 2 secured thereon intermediate its ends. One end of the bar is tapered and more or less pointed, constituting a sharp prong 3, which is utilized in removing or coupling the hooked end of a spring into a hole or opening. The opposite end of the bar 3 is curved or offset slightly, as

shown at 4, and at its extremity is provided with an inturned portion 5 which is wider than the width of the bar and which is formed with a curved recess 6 at its extremity constituting a claw member. This claw member, it will be noted, is disposed at an approximate right angle to the longitudinal axis of the bar I, and at a point removed from the claw end and at the back of the bar I a prong 1 is provided on the bar I, which functions as a stop to limit the movement of the hooked end 8 of a spring 9 on the bar.

In operation, as shown most clearly in Fig. 5 of the drawing, when it is desired to position the hooked end of the spring 9 over a pin or post [0, the claw end of the bar I is inserted through the hook 8 and then the claw is positioned against the far side or face of the pin or post Ill. The bar is then swung in the direction of the arrow shown in Fig. 5, so as to expand the spring 9 and cause the hooked end 8 of the spring to ride down and off the curved or offset portion and off the claw 6 on to the pin or post I0.

In Fig. 6 of the drawing the operation of the prong end 3 of the tool is illustrated, where it will be noted that this prong end 3 is inserted through the hook 8 of the spring 9 and then positioned through a hole or opening II, and when the tool is swung in the direction of the arrow it will cause the hooked end of the spring to ride into the hole or opening ll.

While we have illustrated what we believe to be the preferred embodiment of our invention, it is obvious that various slight changes may be made with regard to the form and arrangement of parts without departing from our invention, and hence we do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claim.

We claim:

A tool of the character described comprising a bar having a laterally and rearwardly offset curved portion at one end of the bar and a claw at the extremity of the offset portion disposed at an approximate right angle to the longitudinal axis of the bar, said claw being wider than the bar and having a concave face conforming to the general curvature of a pin or post, said bar having a spur on its rear face adjacent the offset curved portion constituting a stop to limit the movement of a spring hook on the bar.
